Product Description:

The MAC112C-0-ED-3-F/130-B-0 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. As a motor for analog drives, it operates in position and speed control loops where a tacho signal is returned to a legacy amplifier for closed-loop regulation. Within industrial automation, the unit converts electrical energy into rotary motion that can be synchronized with machine commands for tooling axes, material handling stations, and other continuous-duty applications. Its integrated feedback arrangement supports stable speed control without requiring a separate external velocity sensor.

The motor has a centering diameter of 130 mm, which supports accurate concentric alignment with gearboxes or mounting flanges. The rotor can maintain a nominal speed of 3000 rpm, giving the drive system a broad operating range for common motion tasks. Heat is removed by natural convection, so the installation must allow free surface cooling around the housing. Power enters through a connector on side B, which helps route the cable away from the driven shaft and nearby moving parts. For velocity feedback, the built-in tacho generator produces 3 V/1000 rpm, allowing the analog controller to monitor motor speed in real time during acceleration, steady operation, and deceleration.

The motor has no blocking brake, so the axis requires an external holding method whenever position must be maintained without drive torque. Winding code ED indicates the electrical winding arrangement used for this motor and the matching values expected by compatible drive modules. The motor uses diameter class 112 with length C, which provides a larger internal volume than shorter versions in the same frame family. Operation also benefits from improved tacho smoothness, and the second shaft end for tacho feedback can simplify connection to auxiliary measuring devices or related mechanical components.
